Yang Guang is from Daqing City, Heilongjiang Province. By chance, he saw a magazine report that Shanliwa, deep in the mountains, was struggling to study in a harsh environment and was deeply shocked. 1July, 999, Yang Guang came to Zhaoping Village, Que Town, Daning County to teach. Zhaoping village has a large row of dilapidated houses, which were built in the village in the 1950s. After Yang came, the villagers donated money and materials to build a simple classroom called Sunshine Primary School. In order to improve school conditions, Yang Guang went into the city to buy textbooks for children. He spent all his savings as much as possible; He looked for support and help everywhere. With the support of all walks of life, in September, 2005, a row of red brick and blue tile 14 classrooms and a large courtyard of nearly 2,000 square meters were completed, and Sunshine Primary School took on a new look. The students here come from 27 surrounding natural villages, and the road is far from easy. Every rainy day, he is worried about the slippery road, and the children from other villages can't come, so he goes door to door to pick them up and never delays a class for his children. When some children don't go home at noon, Yang Guang will take on the task of cooking for them at noon, so that parents and children can rest assured. For students from poor families, he must waive all fees and never let a child drop out of school because of poverty.
